CLIFFORD RAY EURLINGAME, OF ST. LOUIS. MICHIGAN.

PIPE-MACHINE.

To all whom it may concern: 1

Be it known that I, CLIrronn it. BURLIN- GAME, a citizen of the UnitedStates, residing at St. Louis, in the county of Gratiot and State ofMichigan, have invented a new and useful Pipe-h Iachine, of which thefollowing is a specification.

This invention relates to machines for making concrete tiles, pipes andthe like and has for its object to rovide a strong, durable andthoroughly e cient machine of this character by means of whichartificial stone tiles may be conveniently and expeditiouslymanufactured.

A further object of the invention is to provide a tile making machinehaving a 1101- low core in ovable to operative position within themolding compartment after the latter has been filled with concrete.

A further object is to provide means for locking the mold in position onthe supporting frame during the operation of the core, and means fordischarging the surplus concrete through said core in the upwardmovement of the same.

A still further object of the invention is generally to improve thisclass of devices so as to increase their utility, durability andefficiency.

Further objects and advantages will appear in the following descriptionit being understood that various changes in form, proportions and minordetails of construction may be resorted to within the scope of theappended claims.

In the accompanying drawings forming a part of this specification:-Figure 1 is a side elevation of a tile making machine constructed inaccordance with my invention. Fig. 2 is a vertical sectional view of thesame. Fig. 3 is a top plan view. Fig. 1 is a per spective view of themold detached. Fig. 5 is a. top plan view of the operating leverdetached.

Similar numerals of reference indicate corresponding parts in all of thefigures of the drawings.

The tile making machine forming the subject matter of the presentinvention comprises a supporting frame including spaced corner posts orstandards 5 connected by transverse and longitudinal braces 6 and 7 andon which is mounted a table 8.

Secured to the top of the table 8 is a circular disk or casting 9 havingan opening formed therein which registers with a cor- Specificaticn ofLetters Patent.

Application filed October 10, 1908.

Patented Feb. 1, 1910. Serial No. 4-.57',166.

responding opening 10 formed in the table, said casting being providedwith one or more lugs 11. arranged to bear against the exterior walls ofthe mold or shell 12. The mold or shell 12 is preferably formed in twosections pivotally united at 13, one of said sections being providedwith spaced hooks 14 arranged. to engage correspolnling eyes secured tothe mating section of the mold, thereby to lock said sections in closedposition. The upper end of the mold 12 is open while the lower endthereof is pro vided with an inwardly extending flange 15 arranged torest on the casting 9 with its inner edge preferably disposed inalinement with the inner edge of the opening 10 in the table. Thepurpose of the flange 15 is to retain the cement or concrete within themoldafter the latter has been filled and tamped and duringtransportation of the mold from the place of filling to the machine.

Arranged above the mold 12 and pivotally mounted at 16 on a pair ofspaced uprights 17 is a cover 18 arranged to bear against the top of themold 12 and lock the same in position on the table 8 during the moldingoperation:

Secured to or formed integral with the lower face of the cover 18 aredepending lugs 19 adapted to bear against the exterior wall of the mold12 and which assist in centering the mold on the casting 9.

Pivotally mounted at 20 on the upright 17 is a locking member 21preferably in the form of av flat bar having its lower end cut away toproduce a shoulder 22 adapted to engage a transverse pin 23 seated in akert or recess 21 in the free end of the cover 18. The locking member orbar 24 is preferably extended longitudinally beyond the shoulder 22 toform a handle or finger piece 25, by means of which the locking membermay be readily moved to operative or inoperative position. The lowerends of the standards 17 are preferably extended through suit- 7 ableopenings in the table 8 and are secured in any suitable manner to atransverse beam or platform 26 disposed beneath the table, as shown. Ifdesired, however, the standards 17 instead of passing through openingsin the table 8 may be secured in any suitable manner to the top of saidtable.

The platform 26 is provided with an opening 27 disposed in alinementwith the opening 10 and in which is mounted for vertical. movement ahollow core member 28. The

by means of which the core 28 may be moved j to operative andinoperative positions. Journaled in suitable bearings 3t secured to thetable 8 is a stub shaft 35 carrying depending lmks 36, which latter passthrough spaced of the yoke 32, as indicated at 38. Attention is herecalled to the fact that the upper edge of the core 28 is inclined orbeveled at 39 to form a cutting edge so that the core ment with thecement will pack the latter against the interior walls of the mold 12 2It will also be and thus form a solid homogeneous tile or pipe ofuniform density wlthout the necessity of tamping the material in themold.

In operation, the cement, concrete, or other plastic material isintroduced within the mold 12 and tamped in the usual manner, afterwhich the mold is placed in position on the casting 9 and the cover 18moved downwardly in contact with the top of the mold and locked inposition by means of the lever 21. The operating handle 33 is thendepressed which causes the core 28 to ascend and enter the moldingcompartment. As the core ascends, the material at the center core intothe receptacle 29, while the inclined edge 39 of said core will compressthe material in the mold and thus permit the formation of a tile orpipe. After the locking lever 21 is released, the lever 33 is operatedto lower the core 28 and the cover 18 is swung laterally against theuprights 17, thus permitting the removal of the mold together with thepipe or tile. Vhen the mold has been removed from the table 8 thelocking hooks 14 are released and the pivoted sections of the mold swunglaterally to open position so as to permit the removal of the moldedproduct. Attention is here called to the fact that the opening in thecover receives the inclined or beveled edge of the core member 28 whenthe latter is moved to elevated or operative position, thereby toprevent chipping or cracking of the cement during the passage of thecore through the same.

From the foregoing description it is thought that the construction andoperation of the device will be readily understood by those skilled inthe art and further description thereof is deemed unnecessary.

Having thus described the invention what is claimed is 1. A machine ofthe class described including a supporting frame, comprising a table andplatform disposed in spaced relation, a disk secured to the table andprovided with a plurality of centering lugs, a apertures 31 formed inthe table 8 and are 1 mold supported on the disk and bearing pivotallyconnected with the opposite sides against said lugs, an uprightextending above the table on one side of the disk, :1 cover pivotallymounted on the uprights and provided with depending centering lugsarranged to bear against the exterior walls of the mold, said coverbeing provided with a central aperture and having a kerf formed in thefree end thereof, a pin extending transversely across the kerf, alocking lever pivotally mounted on the uprights and having its free endformed with a shoulder arranged to bear against the pin for locking thecover in engagement with the mold, a hollow core movable to operativeposition within the mold, and meansfor raising and lowering said core.

2. A machine of the class described including a supporting frame, arelatively stationary mold mounted on the frame, uprights forming a partof the frame, a cover pivotally connected with the uprights, and movableto operative position in engagement with the top of the mold, therebeing a kerf formed in the free end of the cover, a pin extendingtransversely across the kerf, a of the mold will be discharged throughthe lever pivotally mounted on the uprights and having its free endformed with a shoulder adapted to bear against the pin, for locking thecover against swinging movement, a hollow vertically movable corearranged to enter the mold after the latter is filled, and means foroperating the core, there being an opening formed in the cover andarranged to receive the upper end of the core when the latter is movedto elevated position.

In testimony that I claim the foregoing as my own, I have hereto allixedmy signature in the presence of two witnesses.
